Does this mean that you agree with people being used as property and can be passed to one's children (Leviticus 25:44-46) and that a master can beat slaves with a rod, as long as they do not die, because they are his property (Exodus 21:20-21)?
Of 'course I agree with that, slavery has always been necessary thing to make the world go around. Slavery still makes the world go around today, but in a different format. But the basics are the same, the wealthy people employ the poor to do those jobs that educated people don't want to do.
I see slavery as a win win and a very good thing, if you look at the history of the first world countries, you'll find they were all developed by slavery. The wise educated people, took uncivilized nomads from Africa and other places and gave them jobs so everyone benefited. The privative nomads got to learn new skills and their accommodation and meals were all provided.
The lower class still work for the educated elite to this day, it's not called slavery but it's the same thing. The elite buy a factory and employ the lower class, so the lower class get money to feed themselves and the elite get richer so everyone is happy.
